==Key Stage 4==
===Meaning===
'''Reaction time''' is the time it takes between stimulus and response.

===About Reaction Time===
: The '''reaction time''' is how long it takes to react to a change in the environment.
: '''Reaction time''' affects how far a car will travel before the driver applies breaks for an emergency stop, eg if someone jumps out into the road the driver has to see them, think about it and then apply the breaks. This takes time so the car keeps moving at the same [[velocity]] until the breaks are applied.
: The '''reaction time''' of a human can be measured using a variety of experiments where a random event happens and the subject has to respond as quickly as possible. [[experiments.http://www.bbc.co.uk/science/humanbody/sleep/sheep/|Test your reaction time here]]
: Typical '''reaction time''' for a [[human]] is around 0.2 [[second]]s.
